SELF-HEATING SAD-IRON.

Specification of Letters Patent.

Patented Jan. '7, 1913.

Application filed. February 2, 1912. Serial No. 674,895.

To all whom it may concern:

Be it known that I, FREDERICK Sn'r'rn, a citizen of the United States,and resident of Iron Ridge, in the county of Dodge and State ofWisconsin, have invented certain new and useful Improvements inSelf-Heating Sad-Irons; and I do hereby declare that the following is afull, clear, and exact description thereof.

My invention consists in what is herein particularly set forth withreference to the accompanying drawings and pointed out in the claims ofthis specification, its object being to provide simple, economical andefficient self-heating said-irons designed to utilize gasolene or otherhydrocarbon fluid as fuel to the best advantage, and to have each ofsaid irons provided with an airpump permanent therewith in connectionwith the fuel-tank.

Figure 1 of the drawings represents a vertical longitudinal sectionalview of my improved self-heating sad-irons on the plane indicated byline 11 in Fig. 3; Fig. 2, a plan view of the same partly in horizontalsection indicated by line 22 in Fig. 1; Fig. 3, a similar view indicatedby line 3-3 in Fig. 4, one of a pair of baffle-plates in the iron beingremoved, and Fig. 4, a transverse sectional view indicated by line 4-4in Fig. 1.

Referring by numerals to the drawings, 5 indicates the hollow body of myimproved self-heating sad-iron provided upon the interior with upwardlyextending bottom lugs in paired series at intervals longitudinallythereof, those in one series of each pair alternating with those of theother series in the same pair.

Supported on each set of the lugs 6 and 7 is a horizontal baflie-plate 8fastened by screws 9 or other suitable means to certain of said lugs,space being left between an edge of said plate and the adjacent wall ofthe iron. Each bafiie-plate is preferably of sheet-metal folded upon alining of asbestos or other suitable refractory material.

The top 10 of the iron is provided with a front recess 11 engageablewith a screw 12 or other suitable holding device with which the body ofsaid iron is provided. Another recess 13 in the top of the iron engagesa stem 14 extending upward from a side of said iron, and a clamp-nut 15is run on said stem in opposition to said top. However the top may bedetachably secured to the body of the iron in various ways.

An air and gas mixer 16, a fuel-tank support 17 and the handle-bail 18of the iron are fastened by screws 19, 19, to the top of the iron, and arivet 20 may also be employed to connect said tank support with said topof the iron. The shape and disposition of the support 17, as shown inFig. 4, is such as to dispose the fuel tank out of the way of theoperator of the iron, said support and the handle-bail 18 being set ontop lugs 19" of said iron.

The preferably wooden handle 21 of the iron is hollow and engaged by thecylinder 22 of an ordinary hand air-pump that extends through eyesprovided in the bail 18, the heads 23, 23, of said cylinder being inopposition to said bail to clamp the same against the opposing ends ofthe handle. The pump has direct tube connection 24 with the air-valve 25of the fuel-tank 26, that is suitably secured on a support 17 and hasthe partly U-shaped tubular union 27 with the air and gas mixer 16controlled by the usual needle valve 28, said tubular connection being avaporizer. Each side of the air and gas mixer is provided with anairintake port 29, and a burner-shell 30 in connection with said air andgas mixer is perforated at intervals longitudinally thereof to dischargethe mixture opposite the bottom of the iron and under the baffle-plates8, whereby when the mixture is ignited the greatest volume of heat isdeflected upon said bottom of the iron and absorbed by the same and thelugs 6 and 7 thereof, whereby an economy of fuel results. The wasteproducts of combustion find their way up between the bafHe-plates andthe adjacent walls of the iron to escape through side openings in saidwalls under the top aforesaid, the disposition and area of said openingsbeing as herein shown or otherwise as may be found most suitable inpractice.

From the foregoing, the advantage of the baffle-plates is obvious, andby having the air pump a permanent part of the iron it is alwaysconvenient to the operator and cannot be mislaid or lost.

I claim 1. A self-heating sad-iron having a hollow body provided withupwardly extending inner bottom lugs in paired series and at intervalslongitudinally thereof, those in one series of each pair alternatingwith those of the other series in the same pair, a horizontalbaffle-plate superimposed on each series of the lugs clear of the wallsof the iron, and a hydrocarbon burner in said iron arranged between thebaffle plates to have its fuel-discharge openings below the same.

2. A self-heating sad-iron having a hollow body provided with upwardlyextending inner bottom lugs in paired series at intervals longitudinallythereof, those in one series of each pair alternating with those of theother series of the same pair; independent horizontal baffle-platesdetachably secured on the lugs clear of the walls of the iron, and ahydrocarbon burner in said iron arranged between the battle-plates tohave its fuel discharge openings below the same.

3. A self-heating sad-iron having a bail provided at its ends with eyes,a hollow handle between the ends of the bail, an airpump having thecylinder thereof extending through the bail-eyes and the handle, the

heads of the cylinder being in opposition to said bail to clamp the sameagainst the opposing ends of said handle; a fuel-tank supported inconnection with the iron, an airvalve with which the tank is provided,and a tube connecting the pump and valve.

In testimony that I claim the foregoing I have hereunto set my hand atMilwaukee in the county of Milwaukee and State of l/Visoonsin in thepresence of two witnesses.
